2.2.14 spanning-tree max-hops

This command sets the MSTP Max Hops parameter to a new value for the common and internal spanning tree. The

max-hops value is a range from 1 to 127.

2.2.14.1 no spanning-tree max-hops

This command sets the Bridge Max Hops parameter for the common and internal spanning tree to the default value.

2.2.15 spanning-tree mst

This command sets the Path Cost or Port Priority for this port within the multiple spanning tree instance or in the

common and internal spanning tree. If you specify an <mstid> parameter that corresponds to an existing multiple

spanning tree instance, the configurations are done for that multiple spanning tree instance. If you specify 0 (defined

as the default CIST ID) as the <mstid>, the configurations are done for the common and internal spanning tree

instance.

If you specify the cost option, the command sets the path cost for this port within a multiple spanning tree instance

or the common and internal spanning tree instance, depending on the <mstid> parameter. You can set the path

cost as a number in the range of 1 to 200000000 or auto. If you select auto the path cost value is set based on Link

Speed.

If you specify the external-cost option, this command sets the external-path cost for MST instance ‘0’ i.e. CIST

instance. You can set the external cost as a number in the range of 1 to 200000000 or auto. If you specify auto, the

external path cost value is set based on Link Speed.

If you specify the port-priority option, this command sets the priority for this port within a specific multiple spanning

tree instance or the common and internal spanning tree instance, depending on the <mstid> parameter. The port-

priority value is a number in the range of 0 to 240 in increments of 16.
